Spherophakia

What it means

Spherophakia is a rare congenital condition that presents with weak zonules around a more spherical crystalline lens with an increased anteroposterior thickness of the lens, and highly myopic eye. The lens zonules are developmentally hypoplastic and abnormally weak and due to non-attachment of the posterior zonules to the equatorial zone of the lens, the lens changes its normal shape to spherical.
